To (LIZ whom it may concern:

Be it known that I, ALFRED S. CHURTON, a citizen of the Unltecl States,residing at Chica o in the count of Cook and State of Illinois, haveinvented certain new and useful Improvements in Adjustable Heart lights,of which the following is a specification.

The invention relates in general to headlights adapted for use uponlocomotives and particularly upon street railway or electric cars havingfor its broad general object a headlight capable of automaticadjustment, whereby the lights will turn at an angle corresponding tothe curvature of a track over which the ear passes, and will not followthe longitudinal axial line of the car, as is the case where a headlightis rigidly attachei to the car body.

Among the principal objects of my invention is; to provicle a clevicethat is simple arnl economical in its construction and one in which theparts thereof .will Withstand the SllOClS which are imparted to a deviceof this character and will adapt itself to the various angular movementsbetween the car body and trucks With the foregoing and other objects inview, the invention consists broadly eta,

headlight pivotally connected to the car body, capable of being turnei'lupon its pivot, by a suitable gear and shaft connection. transmittingthe angular movement of the trucks of the car to the lamp or lamps.

The preferre embodiment of the invention is herein shown. in theilrawing, in which Figure l. is a sirlc elevational view of a portion ota having my improved device attached thereto. Fig. 2 is a top plan viewor i .5. l, a portion oi? the car hotly being lore-hen a the gear umlpinion connections sin Fig. l. l: oi H 3. of Fig. 3.

lliciierrin; now more specifically to the l 5 a front elevational viewdrawing. the car body (3 has the truolc frame i and wheels 8 securedthereto in the usual manner. saiii truck frame being pivotallyconnector? as a whole to the ear boclvby means oi? ta e truck pivot pin9. Secured. to the holster frame 10 of the truck frame 2" is asegmental.

way. Fig. 5 is a to plan View (it :Wl'l 111 i is a suie cicvatiima! viewl1, partially surrounding the j truck pivot pin 9 and provided withrelatively long teeth 12. The headlight 18 is mounted on a suitablestandard 14, which. i has a pivotal connection with a bracket t that issecured to the car bocly in any well-- known manner. 1 beveled gear 16in mesh with a suitable bevelecl gear 17 at one end of the shaft 18.Said shaft 18 is secured to the under side of the car body by means ofsuitable bearings 19 and carries at its other end a suitable pinion gear20, provided with the pinions ill, which pinions are adapted to be inmesh with the teeth on the segmental g ar 11..

One of the principal features of the invention. resides in the fact thatthe pinions on the gear 520 are so arranged as to some in contact withthe teeth 12 on the 11 at a. point substantially intermediate the lengthof the teeth, for the reason that the truck as a whole has a certain.amount of play and if it were nottor the relatively long teeth, thepinions would become cliserr Q'zlflfll, as by slipping outv of mesh withthe teeth, and thereby interfere with the operation oil-the device.clisengag'inc of the gear 11 from the pinion gear 20, tne teeth on theformer are con struetei'l of coi'isiclcrable length so to mit ofC01lSl(.l8l.'il)lf.-*- n'ioveinent. between the ar hotly and the trucksof said car, with out. disengaging; the 'car anil pinion connection.

It will be readily seen from the toriigoing description. that upon anaugu of the truck frame. as e w gear it will have a cor: movement, whichin. turn, thro gen r LO will impart, a rotatins' j the shaft 18 and.thereby, tl ilfi anil 1? liniii stantarri let. he an 'ar niovcmmit oithe ear trucks will. ini corresponding angular movement. lie-iii'ilighi't3 therel'iy csu ii'm t .oven'ient to always direct its rays upe .i donot. consular n'iv ii' the invent. the broad principle or con. 1s t..v

outta the gears, j l

light, and therefore without confining myse f to the particular detailsof construction herein shown,-

I claim:

1. The combination of a car body and a truck, of a gear secured to thepivot pin of said truck and movable therewith, a lamp mounted upon astandard, said standard being rotatably mounted in bearings secured tosand car body, and having a gear at its lower end, a shaft mounted onsuitable bearings secured to said car body and having a gear at one endin mesh with the gear on said standard, and a pinion gear at its otherend, the pinions of which are arranged in an arc, and in mesh with theteeth of the gear on said pivot pin.

2. The combination of a car body and a truck, of a gear havingrelatively long teeth secured to the pivot pin of said truck and movabletherewith, a lamp mounted upon a standard, said standard rotatablymounted in bearings secured to said car body and having a gear at itslower end, a shaft mounted on suitable bearings and secured to said carbody and having a gear at one end in mesh with the gear on saidstandard, and a pinion gear on the other end of said shaft in mesh withthe teeth of the gear on said pivot pin, the pinions on said pinion gearbeing arranged in an are.

As evidence that I claim the foregoing as my invention I have signed thesame this 23rd day of October, 1909, in the presence of two witnesses.
